No education on Kiosk

Went to McDonalds Maponya, when I got there no one was available at the tills. We waited and the queue got longer as some customers were busy at the kiosk. I went asked why are not being attended to on at least someone must guide the customers and show them how to use it. This guy was standing there forever, he's also not saying that he is struggling. I understand they need to drive the kiosk usage however it must done professionally and not impact customer experience. After I waited and ended up asking someone to attend to us, I was informed there's no ice cream really! Yes we are moving to the era of technology however we still need human intervention. Let's take note of that, please!
